SHOW -BOX COVER.

SPECIFICATION forming part of Letters Patent No. 348,713, dated September 7, 1886.

Application filed Apn'l 9, 1885. Serial No. 161,764. (No model.)

To all whom it may concern.-

Be it known that I, HEINREOK W. BAU- MANN, of Memphis, in the county of Shelby and State of Tennessee, have invented a new and useful Improvement in Show-Box Covers, of which the following is a specification.

The invention relates to the covers used in the retail grocery and other trades, to exclude the dust and insects from boxes of crackers, starch, 850., said covers being usually transparent. Heretofore such covers have been made in one piece to slide off the box or in two halves hinged together, both methods being objectionable on the score of space and liability to breakage.

The nature of my invention consists in a square open frame that may be set on any box of its size. Two pieces of glass are let in this frame, one of which is fixed and the other is capable of being shoved back under the first, and fixed in that position.

In the accompanying drawings, in which similar letters refer to similar parts, Figure 1 is a perspective of a device embodying my invention. Fig. 2 is a partial vertical section on the line 00, and Fig. 3 a partial vertical section on the line y.

Fig. 1 shows myinvention applied to a common cracker-box, G. The cover put on the box by the manufacturer is removed and my frame takes its place. This cover consists of the square frame (I, the fixed glass A, and the sliding sash of glass B. The frame d is made to overlap the box 0, as shown in Figs. 2 and 3.

Fig. 2 shows the construction of the parts to prevent the sliding sash of glass B being drawn completely out of place. This is effected by making the front end of the frame (I too high for it to pass. The end piece, 0, of the sash is recessed to fit over the end of the frame, as shown, securing thus a neat finish when the sash is closed. These boxes are often inclined by the showman, and in this case it is very important the sash should not slide shut by its own weight. To avoid this, the back of the lower sash is made to jam against the inclined lower edge of the upper one when open, as shown in Fig. 3, where A is the upper sash, and B the lower sash wide open and jammed against the upper one.

Show-box covers have been made before to set loosely on the box; but the sash has either been made of one piece to slide out or has been divided and made to open with a hinge. I therefore do not claim the frame (I nor the fixed glass A.

\Vhat I claim is A box-cover consisting of the frame. d, provided with the stationary glass A, in combination with the sliding glass B, substantially as shown.
